Driller providing light and sound stimuli for stimulating the visuosensory and audiosensory nerves, for use in the rehabilitation of postapoplectic paralytic patients

Abstract

A driller device provides controlled intermittent light and sound stimuli for stimulating the visuosensory and audiosensory nerves in the rehabilitation of postapoplectic paralytic patients. Two light emitters are alternately intermittently turned on to stimulate the visual nerves of a postapoplectic patient. Also, electronic buzzers are intermittently operated for sound generation to stimulate the hearing nerves of the patient.

What is claimed is: 
     
       1. A driller device for providing light and sound stimuli for stimulating the visuosensory and audiosensory nerves of a postapoplectic paralytic patient, comprising two light emitters each capable of emitting light of 400 to 2,000 lm for stimulating the visuosensory nerves, said light emitters each being installed at an end of each of a pair of flexible arms each secured at a stem thereof to a control section body, said light emitters being connected to a power source through a controller provided in the control section body, the controller having intermittently on-off operated switch means, and electronic buzzers capable of producing an acoustical output of 50 to 90 phons for stimulating the audiosensory nerves, said electronic buzzers being installed in ear pads of a headphone connected to said control section body, said electronic buzzers being connected to said power source through said controller. 
     
     
       2. A driller device according to claim 1, wherein said controller having said intermittently on-off operated switch means includes a motor and three cams secured at different phase angles to a shaft of said motor, said cams being capable of depressing two corresponding switches for light emitter light generation control and one corresponding switch for electronic buzzer sound generation control, respectively. 
     
     
       3. A driller device according to claim 1, wherein said controller having said intermittently on-off operated switch means includes two motors, two cams secured at different phase angles to a shaft of one of said motors and capable of respectively depressing two corresponding switches for light emitter light generation control, and a third cam secured to a shaft of the other one of said motors and capable of depressing a third switch for electronic buzzers sound generation control. 
     
     
       4. A driller device according to claim 1, wherein said controller with said intermittently on-off operated switch means includes a plurality of semiconductor switches for effecting on-off control of corresponding ones of said light emitters and electronic buzzers, said semiconductor switches receiving respective rectangular wave signals from a plurality of oscillators having different oscillation frequencies.
